*Group* message counts completely off (and not changing) for imap

*Group* message counts completely off (and not changing) for imap

Hi,

I'm using mbsync+dovecot and a .newsrc.eld synced with Syncthing. When I
enter the *Group* buffer, the message count is completely off for the
IMAP folders, e.g. it claims 729 unread for my INBOX that has 21 read
articles and no unread. Another machine claims 1041. Where do the
*Group* counts come from, and what do I do to fix it? I've had issues
with synced .newsrc.eld's before, but typically the numbers were fixed
by just entering and exiting the summary, but no longer.

(but deleting emails makes the counts change)

However, when I do ^ and look at IMAP folders I can subscribe to, it
shows the correct counts in that buffer.

Have you tried `M-g' in the *Group* buffer on a group with incorrect
counts?  This causes nnimap to refresh the info it has on that group.

I have, many times. It has no effect :(

Actually, they're not always correct there either – my INBOX currently
has one message in cur with UID 67:

$ cat .Maildir/INBOX/.uidvalidity 
1484944233
67

$ cat .Maildir/INBOX/dovecot-uidlist 
3 V1484949311 N68 G9afa571227878258553300006656e48d
67 W18869 :1485162486.975_430.tenkjepadda,U=67

but when I do ^, *Gnus Browse Server* shows 67 as the message *count*:

      67: INBOX

while *Group* currently says

      1028: nnimap.fmmbsync.INBOX


-----


This is the secondary-select-method, by the way:

 '(nnimap "fmmbsync"
    (nnimap-address "localhost")
    (nnimap-shell-program "MAIL=maildir:$HOME/.Maildir /usr/lib/dovecot/imap")
    (nnimap-stream shell))

Dovecot has

  mail_location = maildir:~/.Maildir/:LAYOUT=fs:INBOX=~/.Maildir/INBOX

SOLVED! I had

   (setq gnus-use-cache t       
         gnus-keep-backlog 1000
         gnus-directory (~ "/.News"))

and after deleting ~/.News/cache, a "g" in *Group* fixed the counts.
I guess that explains the off-by-about-1000 counts …
Maybe I should put the nnimap into gnus-uncacheable-groups.
